IMPROVEMENT m WEATHER-STRIPS.

Specification forming part of Letters Patent No. 145,820, dated December23, 1873; application filed November 8, 1873.

. To all whom it may concern:

Be it known that I, OLIVER A. VOROE, of Kentland, in the county ofNewton and State of Indiana, have invented a new and Improved AutomaticWeather-Strip, of which the followin g is a specification:

In the accompanying drawing, Figure 1 represents a front view of a doorwith my automatic weather-strip attached, and Fig. 2 a verticaltransverse section of the same on the line 0 c, Fig. 1.

Similar letters of reference indicate corresponding parts.

The invention is an improvement in the class of weather-strips which areso connected with a door as to be operated by the knob-spindle thereof.My invention consists of a weatherstrip, which is raised or lowered in agroove at the bottom of the door, by being connected to the spindle ofthe lock by suitable leverage, so that on opening the door the strip israised and retained in position by a band-spring at the top part, whichlowers the strip on the closing of the door by being depressed thereby.

In the drawing, A represents the outer door of a building, and B thedoor-sill, which is rabbeted in a suitable manner for a metalliccap-piece, a, which projects with its downwardvbent part sufficientlyfar to prevent any moisture from rising from below on the same. The doorA is provided with a groove, b, at the bottom part, in which theweather-strip O, of suitable metal, slides up and down when raised andlowered by a cord or wire, (I, which passes through aperforation orguide-channel, d, of the door, to the arm of a bell-crank lever, D,pivoted to the inside of the door A. The other arm of the lever D isconnected by cords orwires e to the ends of a double lever, E, which isfirmly keyed to the spindle of the door-lock, raising thereby theweather-strip 0, whether the door-knob is turned to the right or left.The arm of the bell-crank lever D, to which the cord or wire (I isattached, is also connected by a cord or wire, f, to a strongband-spring, F, which is applied to the top of door A in such a mannerthat it is depressed. on closing the door in the frame, and elevatedwhen opening the same. Spring F is thereby called, by the turning of thedoor-knob and opening of the door, into immediate action, and retainsthe weather-strip (l in an elevated position, allowing the same to dropdown as soon as the door is closed. The strip 0 passes along thecap-piece a of the door-sill, bearing against the same, and excludingdust and moisture completely, forming thus, in combi nation with thecap-piece a, a very eflicient self-acting weather-protecting device.

Having thus described my invention, I claim as new and desire to secureby Letters Pateht- 1. The automatic weather-strip C, which is raised andlowered in the door A, in connection with the bell-crank lever I),double spindle-lever E, and top-spring F, in combination with thedoor-sill B, having projecting cappiece a, substantially as and for thepurpose described.

2. The combination, with the door and doorcasing, of the spring F, cordsor rods f d, and strip 0, as shown and described.

OLIVER A. VOROE.
